Serial No. 484,615.

To all whom it 'may concern:

Be it known that I, JOSEPH CorLiNKY, a citizen of the United States,residing at Harrisburg, in the county of Dauphin and State ofPennsylvania, have invented new and useful Improvements in Can-Openers,of `which the following is a specification.

This invention has for its object to provide a novel form of implementfor opening cans or like sheet metal packages containing goods ofdifferent kinds, said implement being of such formation as to adaptitself to cans or packages of varying sizes and shapes whether circular,oval or rectangular.

The primary purpose of the invention is the provision of a tool orimplement of the character aforesaid comprising pivoted members formedof telescoping sections, one of said members being provided with acutter and the other member having a centering point or points to fixthe relative position of the stationary member when the implement is inoperation.

A further purpose of the invention is to supply an implement for thepurposes hercin outlined which may be cheaply and economicallymanufactured and comprising parts adapted to be readily assembled andeasily and cheaply replaced in the event of any one of the partsbecoming disabled so as to render the implement unfit for furthereffective service without being repaired.

In the drawings herewith a preferred embodiment of the invention isillustrated, however, it is to be understood that within the scope ofthe invention as claimed, various changes, in the form, proportion andminor details may be resorted to without departing from the spirit ofthe invention.

Referring to the accompanying drawings forming a part of thespecification, Figure l is a. top plan view of a can opener embodyingthe invention, parts being broken away. Fig. 2 is a view similar to Fig.l as it appears from the reverse side. Fig. 3 is a transverse section onthe line 3 3 of Fig. 2 looking toward the pivot pins of the members.Fig. 4 is a detail perspective view of a portion of the handle orrelatively stationary member, the outer portion being broken away. Fig.5 is a perspective view of the cutter member, the handle portion beingbroken away. Fig. G is a perspective view of the intermediate section ofthe cutter member. Fig. 7 is a transverse section on the line 7 7 ofFig. 2.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the sainereference characters.

The two members are designated by the reference letters A and B and arepivotally connected at one end by a pivot fastening l of anyconstruction. Each member comprises a plurality of sections which aretelescopically or slidingly related to admit of the lengthening orshortening of the members.

The member A is relatively stationary when the implement is in use andmay be properly designated as the handle member and it is provided withone or more spurs or points 2. The inner section 3 of the handle memberis provided at one end with a disk or hub 4 which is centrally aperturedto'receive the pivot fastening l. The opposite end portion of thesection S is recessed in one side as indicated at 5 to receive thecooperating section (5 which is slidably mounted therein. Longitudinalgrooves 7 are formed in the walls bordering upon the recess 5 andreceive lugs 8 projected laterally in opposite directions from the innerend of the section G. Grooves 9 communicate at their inner ends with thelongitudinal grooves 7 and extend outward through the recessed side ofthe section 3 and provide passages for reception of the lugs S whenassembling the sections 3 and (3. The outer ends of the longitudinalgrooves 7 are closed thereby preventing outward displacement of thesection G and limiting the outward movement thereof as indicated mostclearly in Figs. 1 and 2. Each of the sections 3 and G is provided witha point or spur 2 which is adapted to penetrate the can or package whenplacing the implement in. position preliminary to operating the same toet'r'ect an opening of the can. The section has a` longitudinal slot 10through which a thumb screw 11 or like fastening passes and which isthreaded into 'the outer end of the section 3. The fastening 11 providesready and convenient means for securing the sections 3 and (5 in anadjusted position.

The cutter member B comprises a series of sections 12, 13 and 1st havinga telescoping arrangement to admit of the member automaticallylengthening or shortening so that the cutter 15 may follow anirregularly shaped can or package when opening the same. The innersection 12 is similar in construction to the section 3 and is providedat'one end with a disk or hub 1G having a central opening to receive thepivot fastening 1, said section having a recess 17 in one side toreceive the section 13 and having longitudinal grooves 1S in the innerwalls thereof bordering upon the recess 17, said grooves being closed attheir outer ends and communicating at their inner ends with lateralgrooves 19 which open through the recessed side of the section 12 andprovide passages for the lugs 2O projected laterally from the inner endof the section 13. The section 13 has a recess 21 in one side extendingthroughout the length thereof and adapted to receive the section 14.Longitudinal grooves 22 are formed in the walls of the section 13bordering upon the recess 21 and receive lugs 23 projected laterallyfrom the inner end of the section 14e The grooves 22 are closed at theirouter ends in a manner similar to the longitudinal grooves 7 and 18 toengage with the lugs 23 and limit the outward movement of the section14. The section 14 is adapted to be placed Within the recess :21 of thesection 13 with the lugs 23 clearing the inner end of said section 13after which the section 1st is moved outward to cause the lugs 23 toenter the grooves 22.

The cutter 15 may be of any construction and is fitted to the section1-1 in such a manner as to admit of its replacement when broken orotherwise rendered unserviceable. A grip or handle piece 24 is tted tothe outer end of the section 1% and a similar grip or handle piece isfitted to the outer end ofthe section 6.

When the component parts of the implement are assembled the toolpresents the appearance substantially as illustrated in Figs. 1 and 2.lVhen it is required to open a can or sheet metal package, one. or bothof the points 2 are forced into the cover or part of the can to beopened thereby fixing the position of the handle member A. The cutter 15of the operating member B is forced through the cover of the canpreferably near the outer edge thereof after which, the handle piece 24of the cutter member B is gripped and moved so as to cause the cutter 15to follow the cover close to the edge or side of the can, thetelescoping construction of the cutter member admitting of the cutter 15following the irregular shape of the cover and always remaining near toand following the side of the can whether the latter be round, square,oblong or of other form.
